Introduction

Innovation drives business but without clear boundaries, it can also drive risk.
Developers and testers often need real data, live systems, and flexibility. But if development, testing, and production environments aren’t properly separated, a simple coding error or misconfiguration could compromise live systems.

ISO 27001 Control 5.30 Development, Testing, and Operational Environments ensures that innovation doesn’t come at the cost of security.

Why Separation Matters

Picture this:
A developer tests a new application patch using the production database “just this once.”
The test goes wrong, wiping real customer data or exposing sensitive credentials.

This control, from ISO/IEC 27002:2022 Section 5.30, is an Organizational control that’s primarily preventive, supporting Confidentiality, Integrity, and Availability through the Protect concept.

In essence  it ensures development and testing are safe playgrounds, while production stays stable, secure, and untouched by mistakes.

What This Control Involves

1. Physical and Logical Separation:

   • Use different servers, databases, and credentials for development, testing, and production.

2. Access Control:

   • Limit who can access production systems; developers should not have unrestricted production access.

3. Use of Sanitized Data:

   • Use anonymized or synthetic data in testing environments to prevent exposure of real customer information.

4. Configuration Management:

   • Implement strict change controls for promoting code between environments.

5. Monitoring and Logging:

   • Log access and activities across all environments to detect misuse or mistakes.

6. Periodic Reviews:

   • Regularly audit environment boundaries to ensure separation remains intact.

Common Risks When This Control Is Ignored

• Test code accidentally deployed to production

• Real customer data used in testing environments and leaked

• Developers with unrestricted production access

• Changes promoted without approval or rollback plans
